Application filed October 20,1920, Serial No. 418,274. Renewed December8, 19 25.

\ I v I a This invention relates to tapered or comcal drinking cups. orreceptacles formed from paper or like material.

Many of the tapered drinking cups in 5 use at the present time, arestructurally weak with a consequent tendency to leak, at the bottom ofthe cup or, as will be termed, the apex. Attemptshave been made invarious ways to cure these defects, in most cases by reinforcing the'cupat the apex with ad ditional material; A reinforcement at the apexunless properly made usually results in the transfer of the weak pointto other adjacent parts of the cup.

An object of this invention is to obviate these-difliculties' andcontemplates the formation of a tapered cup in such a manner that notonly is the apex reinforced and rendered water tight but the adjacentportions of the cup are strengthened and weakness minimized if notwholly eliminated.

A further object is to form the apices of the receptacles at a pointwithin the body of the blanks and from solid stock.

An equally important factor is the use of a blank which may beeconomically cut from the stock, and one which is solid or integral,that is free from cuts or slits which weaken the blank and render itliable to destruction and likewise weakens the cup as well as tending toprovide leaky joints.

To this end a blank substantially quadrantal in form is utilized whichmay be bent and folded flat or assembled and sha ed upon a former intothe finished article eit er by'hand or by machinery, the apices of therece tacles 'bein formed at points within the ody of the blanks fromsolid stock and away from joints in the receptacles when formed.

The blanks are provided with suitable reinforcing portions or tabs andthe arrangement is such that when the blanks are folded the reinforcingparts surround the apices and adjacent parts of the cups, the edges ofthe reinforcing parts contacting with the cups and preferably beingdisposed diag-- onally to the plane of the cups, providing a gradualreinforcement of the cup toward its Instead of using a solid blank forthe cup including the reinforcement as before described, the cup may beformed from two blanks, one forming the major portion or body of the cupand the other the sealing strip and reinforcement for the apex. In

this case neither the blank which forms the the accompanying drawings inwhich Fig. l is a perspective view of the one form of cup completed orassembled.

Fig. 12 is a perspective view showing the use of a sealing strip, widerthan that of Fi s. 9 to 11". 1

0 form the on shown in Fig. 1 a blank substantially qua rantal in formis utilized. The edge 2 of the blank is in the form of an arc struckfrom the center or point 3.

The edge or flange 4 extends from below the center 3 outwardly and meetsthe curved 110 edge 2 and may be consequently termed the chord. The edge5 has an'outer portion 6, which projects radially from the center and aportion which forms a tab 7. The portion or tab 7 is defined by acompound curve having the eoncaved portion 8 and convex portion 9. Thecurved portion 8 unites the outer portion 6 with the convex portion 9and the convex portion 9 unites the edge 4 and con caved portion 8.

, To form the cup shown in Fig. l adhe ive is applied to the edge 4 andportion 7 of the blank and the blank may then be assembled upon a former10, shown in dotted line in Fig. 2, the point 3 being positioned at theapex of the former. The tab 7 is then reversely bent along the line 11toward the body or major portion of the blank. It Wlll be seen that byshaping the tab as before described the blank is then graduallyreinforced toward the apex. The edge 4 is then caused to overlap theedge 6 and tab 7 and the edge 4 and tab 7 are then sealed to the blank,taking the form of a spiral as shown in Fig. 1. It will be observed, seeFig. 1, that the edge 4 and tab 7 when the cup is formed are notcoincident but are separated thereby causing a gradual reinforcement ofthe cup and to a greater extent than if the reinforcement were abruptlymade.

Fig. '4 illustrates a reinforcement of a larger portion of the cup byproviding larger overlapping and tab portions. Otherwise the blank andthe cup formed therefrom is subistantially the same as that of Figs. 1,2 an 3.

Instead of formingthe cup upon a former as just described the cup may beassembled in fiat form. In this case the adhesive is applied in themanner before described and the blank is folded upon itself alon thedotted line 12; the edge 4 is then Faded along the dotted line 13 so asto overlap the edge 6 and the tab 7 and sealed, the tab 7 meanwhilehaving been folded reversely upon the body of the blank along the line11. This folding produces an overlapping portion 14 see Fig. 2 and thisportion 14 is then bent along the line 15 and sealed upon the oppositeface of the blank. The cup having thus been formed may be opened tofinal form for drying.

Figs. 5 to 8 inclusive illustrate a blank and cup which is particularlyadapted to be formed or assembled in flat form.

In this case an integral blank substantially.

then bent upon itself along the line 20 and the edges 16 and 17 sealedforming the sealed portion 21. 1

The blank is then bent adjacent the scaled edges 16 and 17, now termedthe sealed portion, along the line 22 and sealed to the major portion orbody of the blank.

As a result of this folding and sealing of the sealed portion 21 a part23 of the portion 21 extends beyond the blank adjacent the apex, seeFig. 6. This part 23 is thenfolded along the line 24 and sealed to theopposite side of the blank thereby forming the cup, see Fig. 6. It willbe observed in this case, like the cup of Fig. 1 there is a gradualreinforcement of the cup toward its apex, see Fig. 5, this beingpromoted by the tapering of the edge 16 in respect to the line 22 andedge 17 when the edge 16 is sealed adjacent the latter. The cup may thenbe opened as illustrated in Fig. 5 for drying. If desired, however theblank may be assembled upon a former in a manner similar to thatdescribed in connection with Figs. 1 to 4.

The cup shown in Fig. 9 is formed from two blanks, each integral inthemselves, the body of the cup being formed from the major blank 25which is sealed and reinforced by the minor blank 26.

The blank 25 has the characteristics of the development of a cone and isdefined by v the edges 27, 28 and 29, the latter being curved. To formthe cup adhesive is applied to the minor blank 26 and the major blank 25is folded upon itself along the line 30. The two blanks are then broughttogether the apex 31 of the folded blank 25 being located at the point32 offthe blank 26 and the edges 27 and 28 along'the line 33, and unitedby folding the blank 26 along theline 33 and sealing the edges 34 and 35to opposite faces of the blank 25. When this is accomplished a portion36 of the minor blank will project beyond the major blank adjacent itsapex see Fig. 10 and in a manner similar to the part 23 of Fig. 6. Thisportion 36 is then folded along the line 37 and then along the line 38and sealed to complete the cup. When the cup is expanded the edges ofthe minor blank 26 taper with respect to the edges 27 and 28 and serveto gradually reinforce the cup toward its apex, where the minor blankterminates in the form of a spiral, see Fig. 9.

It will be observed that in the several ty es of receptacles abovedescribed, their apices are formed at the centers or points 3, 19, and32, which are located in the body of the blanks and away from pointswhere the receptacles are formed. The apices are thus formed from solidstock which acts to strengthen the receptacles at this point and toprevent leaking.

Fig. 12 shows the use of a wider'minor blank which acts to provide alarger reinforcement of the en The manner of asnected flanges formedonsaid straight edges.

sembling the cup of t is figure is the same as that of assembhng the cupof Fig. 9.

The several cups above described may be assembled from blanks ofwaterproof material or the cups may be waterproofed after completion. 7

Having thus described the invention what is claimed is: 1

1. A blank for a tapered receptacle provided with edges of differentconfiguration formed as a part of a solid blank and adapted to be sealedto each other to form a sealing portion, said sealing portion beingadapted to be folded and curled around the apex of the receptacle andsealed to the major portion of said blank.
